What is the correct position for the barcode on an automation letter concerning the edges of the envelope window?

The correct position for the barcode on an automation letter is 0.125 inches from the edge of the envelope window. This specification is essential for ensuring that the barcode is easily readable by automated sorting equipment used by postal services. If the barcode is positioned too close to the edge, it may be missed by scanners, resulting in delays or errors in mail processing. Thus, maintaining a distance of 0.125 inches allows for optimal visibility and aligns with industry standards for automation purposes. This precise placement ensures that the barcode functions effectively, which is critical for the efficient handling and delivery of the mail.
